Corrosion protective characters of zinc flake
Zinc metal providing cathodic protection against corrosion. Especially, zinc flakes also have the advantage of excellent barrier protection. The barrier effect provides long-term protection while cathodic protection against corrosion is only temporarily.
Cathodic protection against corrosion requires a conductive contact both between the zinc particles themselves. Zinc flakes have a more extensive contact which allows better electrical conductivity and consequently better anti-corrosive properties.
